Answer: 43.6 (Rounded to the tenth)
Explanation: Use the method of: SOH CAH TOA.
Using TOA, T = Tangent.
tan(71) = x/15. Using the butterfly method you can just do the following equation:
15 tan(71) = 43.56 (Rounded to tenth) —> 43.6
3a =18
3a/3 = 18/3
a = 18/3
a = 6

The surface area of the triangular pyramid shown is 94.6 in²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The surface area of the regular pyramid is given as:
Surface area = 3(0.5 * 4.3 * 13) + (0.5 * 4.3 * 5) = 94.6 in²
The surface area of the triangular pyramid shown is 94.6 in²
